You are right Francisco. I was misinterpreting, and probably not having an
"x" is not an issue.

Hi Gökhan,
I think that we are understanding differently the notation (what would mean
that it is indeed confusing). For me 1e-10+3.207e-5 means: "to get your
value read the figure from the axis, multiply it by 1e-10 and add 3.207e-5".
The source of the confusion could be a missing "x" in front of 1e-10.
Anyway the patch that I have submitted is not related to this problem, it
only affects the way the offset is calculated, not the way it is displayed.
I just tested an unmodified version of matplotlib and the "x" is not
displayed there neither. The difference that the patch makes is that instead
of 4x1e-8+2.995e-5 you get 99x1e-8+2.9e-5 that I think it is easier to
read. In addition, if the number of significant figures in the axis range
changes it takes it into account so the offset becomes human friendly for
all the axis values.
Cheers,
Francisco

Hi Gökhan,
I tried your example and I couldn't find anything wrong with the offset
there. However, I agree that this particular mixture of scientific notation
and offset looks confusing. Maybe in that case it will be better to write:
x1e-10+320700e-10 . Is it what you mean?
Cheers,
Francisco
